Georgia Tech quarterback Tevin Washington runs an option play against Southern California during his team’s 21-7 victory on Monday at the Sun Bowl in El Paso, Texas.

EL PASO, Texas — Southern California was ranked No. 1 at the beginning of the season, and Matt Barkley was a strong contender for the Heisman Trophy. The year ended with Barkley on the sideline as the Trojans lost to Georgia Tech in the Sun Bowl.

Tevin Washington threw a touchdown pass and ran for another score to lead the Yellow Jackets to a 21-7 victory on Monday in front of a crowd of 47,922 at Sun Bowl Stadium.

Washington’s 1-yard touchdown run in the third made it 14-7, and he found Orwin Smith for a 17-yard touchdown pass in the fourth.

Barkley, the first three-time captain in team history, injured his right shoulder in a loss to UCLA and was not cleared to play. He clapped as the Trojans (7-6) took the field to face the Yellow Jackets.

Max Wittek tossed a 9-yard touchdown pass to Silas Redd in the second quarter, but also threw three interceptions. Redd also had 88 yards rushing on 17 carries.

David Sims had 99 yards on 17 carries, but he got plenty of help. Zach Laskey added 60 yards on six carries, Lee had 52 on 10 carries and Washington had 16 attempts for 46 yards for the No. 4 rushing team in the nation.

Sims also caught a 3-yard touchdown pass from Vad Lee in the first quarter.

Lee and Washington combined to go just 5-for-10 passing, but two completions went for TDs passes and two more covered 26 and 49 yards and keyed two of the team’s scoring drives.

High-powered USC finished with 10 first downs and eight punts as Georgia Tech shut down the Trojans’ big-play threats all afternoon.

Wittek had four passes deflected at the line. His second interception came in the Tech end zone with 6:22 to go and the last came inside the Tech 10-yard line in the game’s final minute. He was 14 for 37 for 107 yards.

MEMPHIS, Tenn. — Trey Watts rushed for 149 yards, Alex Singleton ran for three scores and Tulsa beat Iowa State 31-17 on Monday in the Liberty Bowl, avenging a season-opening loss to the Cyclones.

Iowa State rallied to beat Tulsa 38-23 on Sept. 1, but the Golden Hurricane put together the comeback in the rematch. Tulsa trailed 17-7 at the end of the first quarter.

The Golden Hurricane (11-3) posted the second 11-win season in school history. Tulsa, which has the smallest enrollment of any Football Bowl Subdivision program, also finished 11-3 in 2008.

Iowa State (6-7) was seeking its second winning season in the last seven years.
